A last series of storms has reached California, delivering additional rain and snow to a state that is already in mourning after the deaths of at least 19 people who were caused by the weather.

In some regions of the state, precipitation in the form of rain and snow was forecasted for Monday night and into early Tuesday morning.

Despite forecasts calling for an improvement in the weather this week, several locations remain in danger of flooding and landslides.

In recent weeks, storms have pummeled California, causing widespread flooding and prompting the evacuation of many cities.

The succession of heavy rains has caused roads to get degraded and trees to be uprooted, which makes it more likely that the next storm will do significant damage as the soil becomes weakened.

The Sierra Nevada range in California received an additional one to three feet (30 to 91 centimeters) of snow during the weekend.

According to poweroutage.us, as of Monday, there were still more than 38,600 customers in the state who did not have power, and there were still over eight million residents on the central coast of California who were under a flood watch.

The National Weather Service (NWS) office in Sacramento predicted that "periods of moderate to heavy snow would persist through Monday." In the meanwhile, Southern California is expected to be hit with persistent and heavy rain throughout the whole of Monday and into the early hours of Tuesday.

In his message to the people of California, Governor Gavin Newsom asked them to maintain vigilance and use "common sense" during the next twenty-four to forty-eight hours.

According to the NWS, the skies will start to appear lighter beginning on Tuesday, but one more burst of rainy weather is expected to strike some locations on Wednesday and continue into Thursday.

On Saturday night, the President of the United States, Joe Biden, issued a major disaster declaration for the state of California, which is the most populated state in the nation.

In California, the magnitude of the destruction wrought by a catastrophic "parade of storms" that occurred once in a generation has begun to become obvious. This "parade of storms" was unprecedented.

A total of 19 persons have been identified as having perished as a result of the flooding, and a youngster of five years old is still missing after being carried away by the waves.

According to the NWS, some areas of California received up to six times the average amount of rainfall between the 26th of December and the 9th of January.

The previous week saw rainfall totals in Santa Barbara that exceeded 410 millimeters (16 inches) in only two days.

Coastal communities like Santa Cruz and San Francisco have been pummeled by storms, which have caused sinkholes to appear in the highways and knocked out the electricity to thousands of houses.

The recent precipitation has led to an increase in the level of water in rivers located around the state. A significant number of low-lying communities that ran along the Salinas River Valley needed to be evacuated.
